Wind River Systems has announced the addition of Signaling Transport
(Sigtran), a telecom signaling protocol, to its WindNet suite of
networking protocols. The company says WindNet Sigtran enables VoIP
network equipment to access the Signaling System 7 (SS7) network
across an IP network, minimizing the need for direct connections to
the SS7 network.

WindNet Sigtran is built around a modular architecture the company
says will allow developers to
select needed components based on specific application
requirements for VoIP infrastructure equipment, including Signaling
Gateways, Trunking Gateways, Media Gateway Controllers, Call Agents,
Softswitches, and VoIP Servers.

The company reports that WindNet Sigtran is integrated with a
variety of complementary WindNet protocols such as SS7, ISDN, SIP,
Megaco and MGCP; and with development tools found in Wind River's
Tornado integrated development environment, the VxWorks and VxWorks AE
real-time operating systems, and the recently released BSD/OS 4.3
operating system.
